In night vision optics, what is the difference between generation 1 and generation 4 ?
Gen 1 use focusing dynodes. In other words the image is transferred and intensified using magnetic and / or electrostatic lenses.
Gen 2,3 and 4 use a microchannel plate. This is like a fiber optic imager. The image to be intensified is focused on the cathode end which consists of many tiny tubes, one per pixel. The electrons are accelerated down the tubes to the anode where a phosphor recreates a brighter image.
